Patented Mar. 21, 1911.

Application filed Becember 8, 1909. Serial No. 532,079.

To all whom it may concern:

Be it known that I, Timooon or! For? TAINE, a subject of the German Emperor, residing at Hanover, in Germany, have invented certain new and useful Improvements in Gas-Generators, of which the following is a specification.

This invention relates to gssgencretors and consists in improvements which apply resting upon a ,30

more particularly to the blast and clinkerclischarging apparatus, butincludc advon' ta ges relating to the construction, fixing and function of the hearth.

A construction embodying these improve ments is shown in the annexed drawings, in which- Figure Iris :1 vertical section of the lower part of the generator, Fig. 2 being a section on the line -B of Fig. 1, and Fig. 3 a sec tion on the line of Fig. 1.

In the drawing or represents a portion of the body of the generator, which is cooled by moons of e. water-jacket a and supported by a perforated flange ring I). The latter rests upon an annular support 0. To the ring 6 is fixed a flange d of a doublewalled, conical hearth e,which is made up of sections prefemhy three and has a flange f ange g of the support 0. The space a between the walls of the hearth is in communication-with the interior of the water-jacket a vIt will be noted that the manner ii which the hearth is supported and fixed allows of easily disconnecting and renewin the same.

The c'inker-pa-n h, which is rotated in the known manner, supports a central blsstr nozzle 2', the orifices In of which are at the ends of helicoidal excrescences formed on the circumferential surface of the nozzle. The faces of these excrescences, in which the orifices 7c are formed am inclined, z. a. recede from the top to the bottom, in order to prevent clogging of the orifices by clinkers. The ducts leading to the orifices are, however, horizontally directed, and the air discharged as indicated by the EH'I'OW-z in Fig. 1 is very uniformly distributed in tho gonemtor. The excrescences form vanes which, during the rotation of the nozzle, serve to break up the clinker and convoy the same downward toward the pan. These rotary vanes co-act' with fixed helical ribs or vanes m formed on the inner surface of the conical hearth, the direction of the vanes on being opposed to the direction of the excrescences. The nozzle forms as it were a complementary portion or the hearth, and ofiords, with the double wall (2, a comparatively large bearing surface for the charge.

The Willi of the pan h is inclined at the same angle as the hearth, and has inclined ribs or vanes 01 formed on its inner surface, to co-cct with o fixed srspcr or abutment 0, for the purpose of discharging the clinker.

What I claim as my invention and desire the, United to secure by Letters Patent of States is I i 1'. In a gas-generator of the class described, in combination with a hearth, and a slag-pan of a central rotary blast-nozzle, a

series of helical excrcscence's formed on the outer surface of said nozzle and formed with air discharge-orifices in faces which recedefrom top to bottom, 2:. series of ribs or veins formed on the inner surface. of the hearth and adapted to cosct with the cxcrescences on said nozzle to hreak up the clinker and convey the some to the slag-pan.

2. In a. gasgenorator of the class described, in combination with a hearth ands rotary blast nozzle, of a. slag-pan harming it conical well and a series of helical rihs or veins formed on the inner surface of Said wall, said slag-pan adapted to rotate with said blast nozzle, and a fixed scraper ing with said slag-pan to dischargoflla clinker therefrom.

In witness whereof I have this specification the presenco ftwo itnesses.
